Otto von Bastler

Otto von Bastler is a central supporting character of Girls und Panzer and the Wundermotor. As a member of the Stahlrattes, he is the head and only dedicated mechanic to the Super Ratte.

Profile
Before he was recruited to be a member of the Stahlrattes, Otto was a famous inventor, credited with revolutionizing Germany's efforts in the war when it came to building tanks.

Personality
Otto is like a coin. He can be kind and caring, willing to do whatever it takes to protect his family. And at the same time, he can be a greedy, selfish Nazi.

Appearance
Otto, for being a high ranking Nazi Official, has been described as looking rather underwhelming. He stands at an average height, wears circular wire glasses, and has a shaved head with short black hair. He typically wears a black Wehrmacht uniform, and for his casuals he just wears a plain white sweater.
